i a citizen of the United S`tates,`and a resident of Norwalk, in the county of Huron and State of Ohio, have invented new and useful Improvements in Washers, of which the following is a` specification.

This invention relates to washers and has particular reference to that class of washers employed as spacing means for flexible rings used in the constructionv of flexible shaft couplings.

An important object of the invention is to provide in a device of the above mentioned character a means whereby the washer as a whole may be securely held in place under varying conditions.

A further object is to provide a device of -the abdve mentioned character which is simple construction and inexpensive to manufacture..

@ther objects and advantages of the invention will be apparentl during the course of the following description.

In the accompanying drawings formin a part of this specification and in which like numerals are employed to designate like partsl throughout the same. n

Figure 1 is a central vertical longitudinal sectional view of a coupling embodying my invention. v

Fig. 2 is a vertical section taken on line 2-2 of Fig. 1,

Fig. 3 isface view of a washer,

Fig. 4 is a vertical section taken on the line 4-4 of Fig. 3, i

Fig. 5 is an edge view of the same, and,

Fig. 6 is a detail horizontal section takenw on the line 6--6 of Fig. 3.

In the drawings wherein for the purpose of illustration is shown a preferred form of my invention the 'numeral 10 indicates a coupling member comprising a plurality of radially extending arms 11 to whichare secured a plurality of flexible rings 12 by means of a bolt 13 passed therethrough as shown. The numeral 14 indicates as a whole a coupling member similar to that indicated 1 p in by the numeral 10 which member comprises a plurality of radially extending arms 15 to which are secured by means of bolts 16, Hexible rings .12. The bolts 13 and 16 carry, be-

wtween the heads thereof and the adjacent flexible ring, washers 17 and 18, respectively.

Between each ofthe flexible rings 12 there to eminem.'

' 'fettfmteeseptftaiici is disposed anelongated J at one 'end' thereof with a ,pair` of' 20` "which `lare bent angularly k with res ect,

to the mainbody-ofthejwasher and Sltely with, .respect l to .Teach 30th one faceof the washer" 19 'thereisproviderdf a plurality of ribs 21 which are struck therefrom to form -a corresponding number ofgrooves upon the opposite sideofA the`face.` 65:

Upon the other face of the washer-there is `provided a plurality of ribs 22 similarto those indicated by the 'numeral ..21. The ribsare struck from thewasher to form upon the opposite side thereof the corresponding number 0f rooves 23. z f' v1n assemb ing the device the :flexible rings i 12, carrying therebetween the elongatedl washers 19, are placed in position as shown inFig. 1. Bolts-13 and 16, lcarrying washers 17 and -18, respectively, are then passed through the flexible rings 12, the washers 19,

and the arms 11 and 15, respectively. The.

nuts carried by these bolts are then runldown upon the same thereby clampingthe'Vv disks securely in place and embedding the; tongues 2() of the washers19 into the ad-- vjacent rings as clearly shown in Fig. 1'. By provided lthese peculiarly designed 'washers the strain o f rotation set up within the coupling as a whole is more evenly distrib uted throughout the iexible washers than4 would otherwise be possible and thev tongues 20 embedded as they are serve to maintain the washers in the desired l positions with respect to 'the flexible rings.

It is* to be understood that the form of my i invention herewith shown and described -is y' to be taken as a preferred example of the same, and that various changesin the shape, size, and arrangement of parts may beresrted to without departing from the spirit o the invention or the scope of the subjoined claims.

Having thus described myl invention, what I claim as Inew and desire to 'secure and protect. by Letters Patent of theuflllnited States, is:

1. The combination with a flexible jrkiiucomprising 'couplin members, and flexi' le rings disposed' t erebetween; bf means for spacing said rings, said means comprising elongated washers provided with ica tongues bent angularly. with respect to the p main body of the washer. y 2. The combination Awith a, flexible coug comprising coupling members, and

fleXi le rings disposed therebetween; of

means for spacing said rings, said means' comprislng elongated Washers pling comprising coupling members, flexible rings disposed therebetween; of means for spacing said rings', said means comprising washers having a plurality of ribs struck therefrom; a plurality of tongues carried by said washer, said tongues being arranged l `angularly with respect to the main body of 15 the Washer.

4:. The combination with a flexible coupling comprising coupling members, flexible rings disposed therebetween; of means for spacing said rings, said means comprisinr washers having a plurality of ribs struc therefrom; a plurality of tongues carried by said washer, said tongues being bent angularly with respect to the main body of the washerl and oppositely with respect to each other.
